CLEANING MACHINE.

Application filed. April 25,

This invention relates to means for cleang a radiator of an internal combustion enne and the water jacket of the engine by flushing the same with a cleansing fluid, the general object of the invention being to provide a tank containing the fluid, with a motor driven pump for forcing the fluid through the radiator or water jacket and returning it to the tank, with means for straining the fluid before it returns to the tank and with means for heating the fluid in the tank.

Another object of the invention is to provide means whereby the fluid can be forced through the radiator or the water jacket in either direction.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which 1 Figure 1 is a side elevation showing the invention in use in flushing a radiator.

1 'Figure 2 is a view of that side of the device opposite to that shown in Figure 1.

Figure 3 is a plan View of the device.

Figure 4 is a view similar to Figure 3, but with the straining tray removed.

Figure 5 is a horizontal sectional view through the lower part of the device.

Figure 6 is a section on line 6-6 of Figure 3.

Figure 7 is a section on line 77 of Figure 4.

Figure 8 is a section on line 8-8 of Fig ure 4.

In these drawings, the numeral 1 indicates a platform supported by the wheels 2 and having the uprights 3 at its ends. A trough-shaped member 4 is supported by the uprights adjacent the upper ends thereof and a tank 5 is supported in the member 4 by the brackets 6 so that a chamber is formed between the bottom of the tank and the member 4. The sides of the member 4 are formed with the openings 7 so that air can enter the chamber.

A tray 8 is supported in the upper art of the tank by the yoke-shaped mem ers 9 and the bracket 10, the members 9 be- 1928. Serial No. 272,787.

ing formed of ipes and one of these members 9 is of su stantially L-shape in plan, as shown in Figure 4. The tray is provided with a large opening 11 and a pair of small openings 12, the large opening havmg 1ts walls formed by upstanding flanges, with a screen 13 covering'the upper part of the opening while the other openings are covered by screens14. Thus the liquid in the tray must reach a level higher than the flange before it canpass through the large opening, but the liquid in the bottom of the tray will drain through the small 0 enings. The tank is provided with a remova 'le cover 15.

Partitions 16 divide the space between the member 4 and the platform 1 into" three chambers, one of which contains a heater 17 which contains a coil 18 and a burner 19. The upper end of the coil is connected by a pipe 20 with a T coupling 21 forming a portion of one limb of the small yoke member 9 andthis coupling discharges" into the tank. The lower end of the coil is connected by a pipe 22 with a T coupling 23 forming a portion of one limb of the other yoke-shaped member 9 and a downward- 1y curved inlet pipe 24 is connected with the open arm of the coupling 23. As shown in Figure 4, the coupling 21 discharges the fluid from the upper end of the coil into the bottom of the tank and the fluid'from the tank passes into the coupling 23 through the pipe 24 from the bottom of the tank a slight distance from the coupling 21. Thus a circulation of the fluid from the tank is set up through the heater so that the fluid in the tank will be heated.

A tank 25 is arranged in one of the other chambers formed by the partitions l6 and this tank contains a liquid fuel under compression and a pipe 26 connects the tank with the burner 19 of the heater, this burner being provided with the usual vaporizer 27.

A centrifugal pump 28 is arranged in the third chamber formed by the partition 16 as is also the motor 29, the shaft of which is connected with the shaft of the pump, as shown at 30. Pi e 31 extends from the intake of the pump into the bottom of the tank 5, the pipe section which is connected with the bottom of the tank being of larger diameter than the other pipes, as shown at 31', to prevent air suction and insure a full flow of water to the pump. A valve 32 is arranged in one of these pipes for controlling the flow of water therethrough. Pipe 33 is connected with the outlet of the pump and passes upwardly through the tank 5, with the discharge pipe 33 arranged to discharge the water into the tray 8. A valve 34 controls the flow of water through this pipe 33. A branch 35 is connected with the discharge line 33 between the pump and the'valve 34 and contains a valve 36. A hose 37 is connected with the outer end of the branch 35. A by-pass 38 connects the branch 35 with one of the pipes 31 and this by-pass is controlled b a valve 39. This by-pass is connected wit the branch between the valve 36 and the hose.

A pipe line 40 enters the upper part of the tank 5 and has its discharge portion 40' extending into the tray 8 and a branch 41 of this line also passes into the tank and has a depending portion 41' which extends to a point adjacent the bottom of the tank. The line 40 is provided with a valve 42 and the branch 41 is provided with a valve 43. A hose 44 is connected with the outer end of the line 40. Both of the hose 37 and 44 have nipples 45 conected with their outer ends and these nipples are connected with the inlet and outlet openings of the radiator or of the Water-jacket of the engine. Figure 1 shows the hose connected with the radiator but, of course, when the Water jacket of the engine is to be cleaned, the hose is connected with said jacket.

I place a baflie plate 46 over the pipe 31 to prevent whirling of the liquid as it enters the pipe so that air pockets will not be formed.

From the foregoing it will be seen that when the hose is connected with the radiator, as shown in Figure l, and the heater started up to heat the cleansing fluid in the tank to the proper degree and then the motor started up, the pump will draw the liquid from the bottom of the tank through the pipes 31 and will discharge the liquid through the lower part of the line 33 into the branch 35 and the li uid will pass through the hose 37 into the ottom of the radiator and after passing upwardly through the radiator, the liquid will return to the tank through the hose 44, the line 40 into the tray and through the screens in the tray into the tank, it being understood that in this operation the valves 34, 39 and 43 are closed and the valves 32, 36 and 42 are open. Thus the cleansing fluid is forced through the radiator and back to the tank by the pump and the foreign matter in the fluid, returning to the tank, is caught and held in the tray.

If the pressure is too great, the valve 34 may be partly opened so that some of the water from the pum can return directly to the tank through t e pipe 33 which discharges into the tray. A pressure gau e 47 is connected with the branch 35 for in 'cating the pressure of the liquid flowing into the radiator and the operator can tell when the passages in the radiator are free by watching this gauge. If it is desired to circulate the cleansing fluid through the radiator from the top to the bottom thereof or in an opposite direction from that just described, the valve 42- the outer part of the branch 35 through the by-pass 38 into the lower part of the line 31 to the pump and the pump will discharge the fluid through the line 33 into the tray.

When the water jacket of the engine is to be cleaned, the hose is connected with the inlet and outlet openings thereof, as will be understood.

Thus I have provided means for heating the cleansing fluid and for forcing it through the radiator or water jacket in elther direction, with means for straining the fluid as it comes from the jacket or radiator so that the fluid will return to the tank free of this foreign matter. As will be seen, the radiator can be cleaned without removing it from the vehicle.

Drain means, shown generally at 48, are provided for draining the pump.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

It is to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What I claim is A cleaning device of the class described comprising a wheel supported platform, a tank thereon containing cleansing fluid, a motor driven pump on the platform, a connection between the tank and the intake of the pump, a valve therein, a connection between the outlet of the pump and the tank, a valve therein, a branch connection from the outlet connection arranged between the pump and the last mentioned valve, a valve in said branch, a by-pass between the branch and the connection to the intake of the pump, a valve in the by-pass, a hose for connecting the outer end of the branch connection with the object to be cleaned, a return pipe extending into the tank, a valve therein, a branch pipe connected with the return pi e between its outer end and the valve, said ranch pipe extending to a point adjacent the bottom of the tank, a va ve in the branch ipe and a hose for connecting the outer end of the return pipe with another part of the object to be cleaned.
